Yeah... the edge detector didn't seem like it was working, so I cut it out and used the solution from SebLague's 2nd video to sync with the clock. The edge detector could fire for too long, or for not long enough, depending on how I was trying to use it.
Right on - I'll have another go.
the solution I had been mulling over was to basically to divide the Real clock by 2, and use that as the system clock, and use the Real clock as a faux rising and falling. It's not really a pulse per say, but it gives the same net effect.
